This invention relates to a new land improved handcarrying frame for heavy objects ysuch as portable gasoline pumping units or lelectrical .generating units.

In many field operations and particularly in combat engineering operations, it is necessary to operate-a pumping unit or electrical generating unit in a location inaccessible to vehicles. Handcarrying is Vthen often a necessityand is always desirable for positioning such a unit. Since these units are usually heavy and relatively compact, it is difficult for the necessary large number of men to get a hold on the unit and still be in a position to lift and walk Vwith the unit, vTherefore,-'the principal object of this invention is to provide a carrying device having telescoping members which when extended are readily accessible t a large Vnumber dof men for hand-carrying, but when notfin use fare retracted to form a compact out-of-the-way frame during 4operation of the unit.

Additional objects and advantages of the invention will be apparent from the following detailed description of the chosen embodiment and the accompanying drawings wherein-f Y Fig. 1 is aside elevation of a carrying device constructed in accordance with the invention showing by y dot and dash lines the position of a portable pumping unit and by broken lines certain features of construction; l

Fig. 4 is a sectional view taken online 44fof Fig. 3 Fig. 5 is a sectional view taken on line 5-5 of Fig. 3; and

Fig. 6 is a top plan View of the device showing thel eight telescoping members extended to carrying position and partially broken away to better show features of construction.

Referring to the drawings, a rigid rectangular box frame is formed by base channel rails 10, base end rails 11, upright tubular members 12, longitudinal tubular members 13, and transverse tubular members 14. A suitable oor or frame is supported by base rails 10 and 11 for supporting the pumping unit. Longitudinal tubes 13 are welded in cradles in the top of upright tubes 12, and transverse tubes 14 being of smaller diameter, pass through the upright tubes and are also welded in place. With this construction, both the longitudinal and transverse tubes have unobstructed inner passages, the advantages of which will be apparent from the followingr structed substantially the same as that shown in FigifS (dotted lines show extended position of tube 15). A

slotted stop disc 16 is rigidly mounted inside the inner end of tube 15. Passing through 'the slot in stop'disc 16 is a guide rail 18 which is rigidly positioned along the longitudinal axis of tube ISbYthe rail support pin 20, which in turn is rigidly attached to the outer tube 13. A stop pin 19Y on rail 18 abuts againststop disc 16 when the inner tube 15 is in extended position, thereby preventing the inner tube from disengaging the outer tube.Y A closed-end cylindrical tube 23 is mounted in the wall of the inner tube 15 kand houses av spring 22 which biasesa ball 21 outward. When the inner tube 15 is in retracted position, the ball `21 is'alignedwith hole 24 which is of smallerl diameter than'theball. This arrangement of ball and' hole provides a snapflock device for holding the inner ftube 15 inV retractedposi-` tion. Whenthe tube 15 isin extended y'position theball 21 is alignedwith hole 25 thereby lockingtubelSin extended position.` A half-disc `17 is mounted in'the outer end of tube 15 to^ serve as a' grip to exert the necessary vforce for unseating the, snap-lock Yball and extending :inner tube 15. `It will `be noted that guide rail 13 is rectangularin cross section'and that the slot in the inner disfc 16is 'of complementary rectangular shapefThis construction prevents innertubeflS from twisting and assures that ball 21,'and holesl 24, ,25V

scribed is preferably made of aluminum alloy to reduce the Weight of the device.

The tubular construction described above provides a light-weight, relatively rigid protective framework about the unit, in addition to'provviding the required tensile strength for lifting theunit,Y by taking advantage of the high rigidity strength per unit weight inherent in tubular construction. The novel manner in which the upright, longitudinal, and transverse tubular members are interconnected utilizes tubular construction and at the same time provides `free passageways in the horizontal memberslfor thel telescoping inner tubes.

When the pumping unit is being operated, the eight` inner tubes remain in retracted position which results in l a rectangular framework about the unit only slightly larger than the unit itself. With the inner tubes in this position, there are no projecting members to endanger the operating personnel. When it is desired to move the unit, the inner tube is extendedby pulling on the half-disc 17 which unseats the snap-lock ball. The inner tube is extended until stop-disc 16 abutsy stop-pin 19, at which time the snap-lock ball again seats in hole 25.

The inner tube cannot be extended to the point that it disengages the outer tube, and the snap-lock device prevents the tube from sliding back into the outer tube. Of course, any number of tubes can be extended, and the tubes are so arranged that as many as eight men can conveniently lift the unitrand still be in a position to walk.

I claim: l. A carrying device comprising a rectangular base frame, a vertically disposed upright tubular member attached adjacent to each corner of said base frame, each of said upright tubular members having a passage therethrough in the transverse direction and a saddle at the upper end thereof aligned in the longitudinal direction, a plurality of horizontally disposed outer tubular members each received in and attached to the saddles of a pair of upright tubular members, and a plurality of horizontally disposed outer tubular members each received in and attached to the passages of a pair of upright tubular members, aA pair of oppositely extending inner tubular members received in telescoping `engagement with each of said outer tubular members, a disc rigidly attached inside and adjacent the inner end of each of said inner tubular members, said disc having a poy lygonal-shaped aperture therein, a rail of corresponding polygonal cross section for each inner tubular member connected to and disposed in each of said outer tubular members, .said rail having a segment of enlarged cross section adjacent the outer end thereof, said rail passing throughsaid polygonal-shaped aperture and cooperating therewith to prevent rotation ofV said disc, ,and said rail extending into said inner tubular member whereby said disc travels relative to said rail and abuts said enlarged segment when said inner tubular member is extended.
